I have wondered this for a while, and now I am actually thinking of making this style of video. I would like to know the easiest way to do this, and any tips are must appreciated. Due to my most likely confusing wording, I have included a youtube video in this style (with a beautiful piece as well!)https://www.youtube.com/watch?v=RswBfSu ... e=youtu.be
Thank you for any help; it is much appreciated!

if you just want stills (and no "play along" thing) you just need screen shots of the music, an audio file, and the patience to pinpoint how long each section of the sheet music lasts. Imovie or any other basic video editing software can handle this
